# Many elements install additional distribution packages.
# In addition the user can provide a set of packages to be installed
# via the '-p' switch.
# Some of them influence the boot process and therefore the initramfs
# needs to be updated. Because the package manager during the image
# creation process is configured not to run package scripts, this needs
# to be done explicitly.

# Please note that the 'dracut-regenerate' element does a similar job.
# Nevertheless the update-initramfs / mkinitramfs are (currently) the
# standard way for Debian / Ubuntu.
# Also the 'dracut-regenerate' element can currently (Sep 2017) not
# be used with Ubuntu, because of some problems, e.g. it clashes with
# the ubuntu-minimal distribution package (not the DIB element with
# the same name).
